Our website uses cookies. A cookie is a file that contains an identifier (a string of letters and numbers) that is sent from a web server to a browser and is stored by that browser. The identifier is then sent back to the server each time the browser requests a page from it. Cookies can be either 'persistent' cookies or 'session' cookies: a persistent cookie will be stored by the browser and will remain valid until its set expiry date, unless deleted before that date; on the other hand, a session cookie will expire at the end of the user session, when the browser is closed. Cookies do not usually contain information that personally identifies a user, but the personal information that we store about you may be linked to the information stored in and obtained from cookies. On our site, we use both persistent and session cookies
